    For 2D tiling you need the kernel patches and drm, xf86-ati and mesa from git.

    Update your libdrm with one from git and test again, if there is still an issue please open a bug

    That's not entirely true, for mesa 8.1 you need new libdrm it's a requirement. If you have and old drm/ddx you will still get 1d tiling by default which was not the case previously. If you have proper kernel you will get 2D tiling for texture and then if you have ddx and enable option you will get 2D tiling for front buffer and zbuffer.

    Ok, thanks for the explanation

    Default Hmm, I bet these results are just for enabling 1D tiling then

    Michael doesn't say anything about patching the kernel, and it's listed as a 3.3.0-999 generic version which i assume is the default from Ubuntu.

    Now I'm curious how much further 2D tiling would do, assuming it isn't on. + PCIE2. Seems like there's a lot of different options for the radeon drivers that provide large performance boosts but are turned off by default. Hopefully that starts to change.

    Depends on the app, 20-30% perhaps.

    That's not bad, except that a lot of games should be many many times faster than that, at least compared to the blob.

    Pretty sure he is using 2d tiling at least for texture. I can't think of anything else that would explain perf increase.

    There's a new video with 800x600 instead of 1600x900: http://www.youtube.com/watch?v=E_TDriMsCZk

    However, I did try WoW starter edition under Windows, and it was barely playable, 30 FPS with lowest quality settings. I believe you could expect similar frame-rate with HoN under Linux with the proprietary drivers, but with mesa it would most likely be completely unplayable.
    If you want I can give it a try when I get home tonight and give you the exact numbers.
    That would be nice!

    At the moment I play this game on a Pentium SU4100 and its quite ok on lowest settings(on Windows, I will try it with Ubuntu 12.04 again).
    So I am wondering, if this would run better on a E-450(on Linux obv). I think it should do so. The gpu should be way better then a Intel GMA.
    If not, I will wait til Trinity.
